MAIN FEATURES of RC-NUT

rc-nut_diagram

Made from Chrome-Molybdenum Steel

Nut body is made from chrome-molybdenum steel and provides superior strength and durability. It also has low thermal expansion property, and minimizes the chance of a stud seizing under high-temperature.

Stabilized Fixing Torque

Steel floating collar reduces irregular friction between wheel and nut caused by rough surface, and thus stabilizes the torque.

Cotrolled Torque over Years

Steel floating collar minimizes scarring on contact area between wheel and nut, and consequently helps to apply same torque every time.

Easy Fastening

Special thread design helps to mate the thread quickly and securely.

FIA Grp.N Regulation Complied

All the materials are ferrous in order to comply with FIA Group N regulations.
